Posterior circulation ischemia mainly refers to insufficient blood supply to the cerebellum, brainstem, and temporo-occipital lobe, which needs to be comprehensively evaluated by its symptomatic manifestations, physical characteristics, and neuroimaging examinations. In recent years, posterior circulation ischemia has been defined as a group of clinical syndromes, basically eliminating the diagnosis of posterior circulation ischemia.
1. Symptoms: The main symptoms of posterior circulation ischemia may include dizziness, numbness of facial limbs, slurred speech, and visual impairment.
2. Characteristics of signs: posterior circulation ischemia may be accompanied by special signs such as oculomotor disorders, sensory abnormalities, gait ataxia, swallowing disorders and so on.
3. Neuroimaging examination: in order to make a clear diagnosis, patients can under the guidance of specialized physicians carry out comprehensive assessment of imaging examinations such as cranial MRI scanning, CT angiography, transcranial Doppler ultrasound, etc. At the same time, vestibular examination can be perfected, except for otogenic dizziness.
It should be noted that the poor condition of the posterior circulation vessels may not necessarily mean that the posterior circulation ischemia, and should be combined with the clinical. At the same time, it is not reasonable to diagnose simple chronic dizziness in the elderly as posterior circulation ischemia.
If you feel unwell, you should go to the hospital in time for relevant examinations to clarify your condition and actively cooperate with the doctor’s treatment.
